Bug Description

In this particular case, I wanted to do some more complex groupby and ordering on a large slowlog which requires a lot of memory.
In order to be able to do this without gigabytes of memory and hours of wait time, I wanted to filter out most of the data first and create a smaller slowlog
But unfortunately all that data is lost when doing --no-report --output slowlog

What is lost:
- SET TIMESTAMP
- Time microsecond precision
- Rows_affected
- InnoDB_trx_id
- hostname
- Rows_read
- Bytes_sent
and many many more :(
